BEAN-SHELLING DEVICE.

Application filed October 5, 1920. Serial No. 414,841.

To all whom it may concern:

Be it known that I, MICHAEL MoLNan, citizen of the United States,residing at Cleveland, in the county of Cuyahoga and State of Ohio, haveinvented new and useful Improvements in Bean-Shelling Devices, of whichthe following is a specification.

This invention relates to a bean shelling device, or thresher, and theobject is to provide a device by means of which the beans or peas to beshelled may be effectively removed from the pods, and discharged to asifting screen, and discharged thence to a or other receptacle.

1 A further object is to provide in a device of the type indicated, arotary device having teeth on the surface thereof, or on both surfaces,for cooperation with teeth formed on a stationary element or elementsadjacent to which the rotary element operates.

A still further object is to provide means for yieldingly mounting therotary element, permitting the latter to be used in shelling varioussizes of beans, without damaging the latter by abrasion.

"With the foregoing and other objects in view, the invention consists inthe novel construction, combination, and arrangement of elementshereinafter described and claimed.

In the drawings, Figure 1 is a view of the device in side elevation,Figure 2 is an elevati'on from another angle, Figure 3 is a detail insection of the screen and the mounting means therefor, Figure 4: is adetail in section showing the mounting of the spring for the yieldingmovement of the rotatable element, Figure 5 shows a portion of therotatable element in side elevation, and Figure 6 is an elevation of aform of the device in which teeth are provided only on one side of therotatable element.

In carrying out my invention, I employ an upper frame 10 mounted on asuitable support or supports, such as legs 12. EX- tending upwardly fromthe frame 10 are vertical elements 14: supporting a box like receptacle15 for receiving the beans to be shelled.

This receptacle 15 is provided with openings 16 having communicationwith hoppers 18, whereby the material is brought into position to beacted upon by the shelling devices per se.

A rotary disk 20 is provided with radial series of teeth or projectingelements 21, on both sides thereof, these teeth cooperating with teeth22 on the stationary disks 23. The stationary disks are suitablysupported, as by means of brackets 24 connected with frame 10. It willbe understood that the respective series of teeth of the stationary elements and the rotary element are so spaced that the teeth on latter passbetween those on the former.

The rotary disk 20 is supported on a shaft 25 having its bearings at 26and 27 in the stationary disks, and the shaft carries on one end a crankelement 28 connected by pitman 29 with a screen 30. This screen ismounted for movement about its central longitudinal axis, pins 31 and 32connected with the end members of the screen being received by bearings31 and 32 supported by the frame. The screen is inclined as shown, andthe beans pass to a receptacle beneath the frame 10, the Waste materialpassing off from the lower end of the screen.

A fly wheel 10 is mounted on shaft 25 and also a pulley 41 driving abelt 42 passing over pulley 43 on shaft 44 of the rotary fan 45, thelatter serving an obvious pur pose in the operation of the device.

In the drawings, I have also shown a single acting machine, in which therotary disk 20 is provided with teeth on one side only, for cooperationwith the teeth of the stationary disk 23. Shaft 25 carries the rotatingdisk.

In order to make it possible to use the device for shelling beans ofdifierent sizes, I provide for the yielding of the rotary disk, so thatbeans or peas of large size may be shelled without being damaged by theteeth. This yielding movement is made possible by the use of a spring36, mounted as shown.

hat I claim is In a device of the class described, a rotatable elementhaving teeth formed on the surfaces thereof, a stationary element spacedfrom the rotatable elementand being disposed in a plane paralleltherewith, said stationary element having teeth cooperating With thosefirst named, resilient means for controlling the cooperation of thetoothed elements, a hopper for feeding material toward the rotatableelement, a second stationary element having teeth thereon, and

located on the side of the rotary element opposite-to thestationaryelement first named, and a second hopper for feeding material be-
